ISO 9856:2018 is an international standard that provides guidelines for the calculation
of conveyor belt capacity, as well as the determination of belt tension, power requirements,
and the selection of appropriate belt construction. This technical article aims to provide
an easy-to-understand explanation of ISO 9856:2018 and its significance in the industry.
The Importance of Conveyor Belt Capacity
Conveyor belts play a crucial role in various industries by transporting materials efficiently
from one point to another. The capacity of a conveyor belt refers to its ability to handle a specific
amount of material within a given time frame. ISO 9856:2018 provides a standardized approach to
calculating conveyor belt capacity, ensuring uniformity and accuracy across the industry. By
adhering to this standard, companies can make informed decisions about conveyor belt selection
and optimize their operations for maximum efficiency.
Determining Belt Tension and Power Requirements
Proper tensioning of conveyor belts is essential to ensure smooth operation and prevent slippage
or damage to the belt. ISO 9856:2018 specifies methods for determining the initial tension of the
belt and calculating the required power for driving the belt. These guidelines take into account factors
such as belt length, speed, and load characteristics, allowing engineers to accurately calculate the
tension and power requirements for optimum performance. By following these guidelines, companies
can prevent costly downtime and extend the lifespan of their conveyor belts.
Selecting the Right Belt Construction
Choosing the appropriate belt construction is vital to ensure the durability and reliability of conveyor
belts. ISO 9856:2018 offers guidance on selecting the right belt type based on factors such as the
operating environment, material characteristics, and load conditions. This standard defines various
belt properties, including tensile strength, elongation at break, and adhesion between layers, helping
companies make informed decisions when it comes to belt selection. By using belts that align with
ISO 9856:2018, companies can minimize the risk of belt failure and maintain smooth operations.
